You mention two examples of a person apparently attempting to commit suicide:

1.  Jumped off bridge into river, but landed in mud on banks

2.  Jumped in front of train, but only got broken arm

These examples show such incompetence, that I can't believe the attempts were genuine.

More likely, they were a cry for help. Which could have been better answered, if the person had gone to their GP for some sedative pills, like Prozac.   Or started drinking a few cans of strong lager each day, chilling out, and reflecting on life.

Instead of jumping off things theatrically.  Who needs such silly antics - aren't they too daft for any serious person to even consider?
